Migration and Spatial Ecology of the Spanish Populations of Scopoli's and Cory's shearwaters (Migración y ecología espacial de las poblaciones españolas de pardela cenicienta)
Abstract and Figures
This book has been published by the Spanish Society of Ornithology (SEO/BirdLife) in the framework of the MIGRA programme. In this work we analyse the movement ecology and at-sea behaviour of two related seabird species under conservation concern: the Scopoli's and the Cory's Shearwater. It focuses on Spanish populations, covering the entire distribution range of the species in the country. A large set of remote tracking data was compiled in order to get critical knowledge to enhance conservation status, including data from 6 years and 13 breeding colonies, more than 300 year-round journeys and more than 1,500 foraging trips. We present the main insights regarding at-sea ecology and year-round movements, including: the identification of the foraging grounds, resting areas and commuting corridors during the breeding period; the characterization of migratory phenology and main migratory flyways; the location and characteristics of the wintering quarters; the migratory conectivity; and the differences in at-sea behaviour by population and wintering area. Moreover, we provide to non-specialized readers an introduction to technical details of remote tracking systems employed in order to ensure a correct interpretation of results and figures. The book was conceived to reach out scientific but also out-of-science audiences, such as environmental managers, and for that reason the main text does not extend in details about methodology. Many figures and animations are provided to reach broader public. The book is written in Spanish, but captions of figures and tables remarking the main findings, as well as an extended summary, are provided in English.
